Hi! I'm currently searching for a pair of headphones that have these qualities:

Good sound quality

Detachable cable

Closed or Circumaurul

Comfortable

Comes with a hardcase

Good isolation

Stylish (doesn't have to be as long as all the other requirements are fulfilled)

Also I don't plan on buying an amp so it has to have good sound quality without it.

Thanks

Heya,

Budget?

Note: You can get a hard case separate. So focus on closed/isolation/detachable cable/comfortable.

My first thought is a Brainwavz HM5 or Fischer Audio FA-003 (same headphone). It meets all requirements except that the case has thick foam and is soft, but firm, instead of directly "hard." But you can get a hippocase if you want it hard.

Also, "closed" is not the same thing as "circumaural" - closed means the earcups are solid/closed, while circumaural means around-ear or over-ear (as opposed to on-ear (supraaural) or in-ear (IEM)). You can have a circumaural and open can, like the Koss PRO4AAAT, or a circumaural and closed can, like the Koss MV1.

If we let "good sound quality" be entirely relativistic (you'll have to be more specific), there's a few options that come to mind when also considering mobile use:
- Bose QC15
- Beyer T70p
- M-Audio Q40
- Ultrasone (various models; DJ1, DJ1 Pro, HFI-780, PRO900, etc)
- Koss (various models; TBSE1, MV1, etc)
And so on (and what MalVeauX said).

As far as cases go, I think HeadRoom still sells a few, and I know Koss has some cases available as well. Finally, you can buy the Ultrasone, Bose, and Beyerdynamic cases as spares from the manufacturers direct - I think they're all right around $30. The Bose, Koss, and Ultrasone cases will require a headphone that can fold flat for storage, the Beyer cases just need something that fit in the foam cut-out.

Well, how do you want your sound presented? Do you like your bass "boomy" and big, or tight and complimentary? Do you like your mids (stuff like vocals and non-high pitched guitars.) loud or quiet? How do you want your headphone to sound, I guess is what I'm getting at.
